# Command: var get
The `var get` command is used to get the contents of an existing variable.
## Usage
```plaintext
nomad var get [options] <path>
```
If ACLs are enabled, this command requires a token with the `variables:read`
capability for the target variable's namespace.
## General Options
@include 'general_options.mdx'
## Output Options
- `-item` `(string: "")`: Print only the value of the given item. Specifying
this option will take precedence over other formatting directives. The result
will not have a trailing newline making it ideal for piping to other
processes.
- `-out` `(enum: go-template | hcl | json | none | table )`: Format to render the
variable in. When using "go-template", you must provide the template content
with the `-template` option. Defaults to "table" when stdout is a terminal and
to "json" when stdout is redirected.
- `-template` `(string: "")` Template to render output with. Required when
output is "go-template".
## Examples
Retrieve the variable stored at path "secret/creds":
```shell-session
$ nomad var get secret/creds
Namespace = default
Path = secret/creds
Create Time = 2022-08-23T11:14:37-04:00
Check Index = 116
Items
passcode = my-long-passcode
```
Return only the "passcode" item from the variable stored at "secret/creds":
```shell-session
$ nomad var get -item=passcode secret/creds
my-long-passcode
```
